My dog won't leave me alone.

Okay, so I didn't know where else to post this. I love my dog SO much. She is like my child. My husband and I have two other dogs, so in all we have 3. My girl, Daisy, is the oldest and I've had her the longest, got her before my husband and I met so I would say she's the most attached to me/spoiled. Anyways, long story short SHE WILL NOT LEAVE ME ALONE. She is always following me around, needing to be IN my lap or on me in some form more than normal. I mean she's always followed me around but now she always has to be touching me, to the point that I'm starting to get irritable. I know she means well but should I take her to the vet to see if something is wrong mentally? Or can she sense all these hormones going through my body? My doctor has me on Prometrium to regulate my cycles. I just don't know if I should be concerned or if she can sense something that I can't.
